IMPROVEMENT IN COAL-OIL LAMPS.

Specification forming part of Letters Patent No. 39,55 l, dated August18, 1863.

To all whom it may concern:

Be it known that I, COOPER E. OORBETT, of Oorbettsville, Broome county,State of New York, have invented a certain new and useful Improvement inGoal-Oil Lamps; and I do hereby declare that the following is a full andexact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecication, in which- Figure lis an exterior view of the lamp; Fig. 2,a view of the top end of the tubes and wick, and Fig. 3 a section of thetubes and Wick.

T T is au outer tube inolosing packing a a, o."cotton or other poroussubstance, which surrounds the inner tube. The inner tube, fllled withthe ordinary Wick W, is constructed as uslal. The outer tube, T T, isprovided with lips L L, which are bent over the top of the packing,leaving openings as at P P P P for the flame. These openings may bevaried according to the amount of ame or light required. The outer tubemay be made of a single piece ot' sheet metal cut out the proper shape.

The object of surrounding the ordinary tule and Wick with packing ofcotton or other porous substanceis to absorb the surplus oil thatusually overflows the wick-tube and causes the disagreeable smokingwhich takes place when a chimneyis not used. By this arrangement thecoal-oil lamp may be used Without a chimney, and will be very useful asa handlamp for the house, and suitable for railroad or other lanterns.

What I claim as my invention, and desire to secure by Letters Patent,is-

Surrounding the tube of the ordinary coaloil lamp with packing of cottonor other porous substance, as and for the purposes described.
